SPANNER.

SPECIFICATION formingpart Of Letters Patent NO. 674,778, dated May 21,1901 Application filed October 27, 1900. Serial No. 34,666. (No model.)

To all whmn it may concern:

Be it known that I, FREDRICK OsoAR LA- GERBECK, a citizen of the UnitedStates of America, and a resident of the borough of Brooklyn, city,county, and State of New York, have invented certain new and usefulImprovements in Spanners, of which the following is a specification.

My invention relates to spanners of the kind in which two spurs or studsare employed in connection with a handle for engaging sockets or a nickin the head of the screw or other object to be turned; and it consistsof an improved and simpler and cheaper construction for adjustability ofthe spurs or studs for adaptability to screw-heads or other such objectsof different sizes and also for renewing the spurs or studs when broken,as hereinafter described, reference being made to the accompanyingdrawings, in which- Figure l is a plan view of my improved spanner witha part in section. Fig. 2 is a longitudinal section with a nickedscrewhead, showing the application of the spanner to it. Fig. 3 is atransverse section on line 3 3, Fig. 2. Fig. 4 is a detail inlongitudinal section, showing the application to a screwhead havingsockets for the studs or spurs of the spanner.

In the first place I take a suitable rod or bar of iron, preferably ofround cross-section, and bend it double, as represented by a a, forminga loop-head b and two parallel guideways, between which I fit a suitablecross-head 0, so as to be retained in the guideways with freedom toslide toward and from the head 12. Through said head and perpendicularlyto the plane of the two members a I insert a stud-pin cl, with aprojecting spur e, and through the cross-head I lit a like pin d, alsowith a projecting spur e, and provide a set'screwf to each pin forsetting them in position.

l/Vith the crosshead I provide an adjusting-screw g, swiveled to it at hand extending along between the two members a into a chambered handle2', attached to the ends of said members a and through an adjustingthumb-nutj, fitted in a slot. of the handle at the ends of the membersa, so that by turning the nut one way or the other the crosshead may beshifted accordingly with relation to head I), and thereby adjust thespurs relatively to each other.

The handle is in this example represented as consisting of two equalparts stamped into the required shape and dimensions and riveted to theparts ct, as indicated at I. They may be otherwise constructed andfastened to said parts and to each other as desired.

What I claim as my invention is- 1. The combination of the rod or barbent double at the middle and forming two parallel members joined by theloop of the bond, with a slideway between them, a handle attached to theends of the two parallel mem bers, a cross-head arranged on the slidewaybetween the handle and the loop of the bend, an adjusting-screw swiveledat one end in the cross-head, a thumb-nut located in the handle at theextremities of the two members, and traversed by the adjusting-screw,and the studs in the loop of the bent rod and the cross-headrespectively.

2. The combination of the rod or bar bent double or thereabout at themiddle and forming two parallel members joined by the loop of the bend,with a slideway between them, a handle attached to the ends of the twoparallel members, a cross-head arranged in the slideway between thehandle and the loop of the bend, an adjusting-screw swiveled at one endin the cross-head, a thumb-nut located in the handle at the extremitiesof the two members, and traversed by the adjustingscrew, and the studsin the loop of the bent rod and the cross-head respectively, and be ingadjustable thereon and provided with means for setting them fixedly.

Signed at New York city, New York, this 10th day of September, 1900.
